Which option may I choose in case I was insured in my home country according to my employers requirements? Is there any to circumvent the penalty for being uninsured?

Did you move into or out of the US in 2018?  If so, which one and what date in 2018 did you move in or out of the US?

If you were only in the US for only 5 months, you were a nonresident for US tax purposes in 2018. 

TurboTax does not support nonresident returns.

However we have a partnership with Sprintax offering a nonresident tax filing solution to our TurboTax customers.

Visit the TurboTax/Sprintax site for more info or to get started.

 As a nonresident of the US, you are not subject to the healthcare insurance penalty.
